SPECIFICATION forming part of Letters Patent No. 672,476, dated April 23, 1901.

Application tiled October 3,1900. Serial No. 31,902. (No model.)

.To all whom t may concern.'

Be it known that I, EUGENE OsBoRNE ED- WARDs,of La Crosse,in the county of La Crosse and State of Wisconsin, haveinvented certain new and useful Improvements in Grain-Drills; and I do hereby 'declare the following to be a full, clear, and exact description-of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improved seeddrill, one object of the invention being to provide a seed-drill with improved mechanism for raising, lowering, and regulating the spring pressure of the furrow openers or shoes.

A further object is to provide a drill with improved supporting frame which will be rigid and strong and maintain the operating mechanism ofthe drill always true.

A further object is to so construct a seeddrill employing a divided axle that the major portion of the weight of the seedboX will be disposed some distance laterally from the bearing of the inner ends of the axle-sections, and thus prevent the latter from sagging.

A further object is to provide a seed-drill which will be simple in construction, in which broken or injured parts can be readily removed and replaced, and which will be of the minimum draft when in use.

With these objects in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings; Figure 1 is a view in section illustrating my improvements. Figs. 2 and 3 are views of the seedboX lla. Figs. 1I, 5, 5, and 6 are views of details of construction. Fig. 7is a plan view of the frame, and Fig. 8 is a rear elevation of a portion of the machine.

The frame of my improved drill comprises parallel longitudinal angle -irons l, having bearings secured to them at their rear ends for the aXle 2 and connected at their forward ends and between their ends by transverse angle-irons 3 and 4, respectively, and suitable metal braces 5 are provided between angle-irons 3 and 4 to strengthen the frame.

The axle 2 is made straight and in two sections when `the machine is of any considerable width, and the inner adjacent ends of the axle-sections are supported in an elongated bearing 6 on an angle-iron arm 6, secured at its forward end to the iron 3 and connected with iron L by block '7, so as to form a rigid bearing for the inner ends of the axle-sections. It will be seen that by making the axle in two sections the mechanism connected therewith can be operated independently,and thus greatly relieve the operator.

On each side of arm 6 and some distance laterally from said arm and central bearing 6a and irons 1 are provided angle-iron arms or stubs S, secured at their forward ends to front cross-iron 3, and have secured to their rear ends castings 9, having bearings for the reception of the aXlesections. Divergent lugs 11 project upwardly from castings 9 and bars or straps lle and lld connect the lugs with the seedbox 11a, which latter is supported at its ends by straps connecting it to the irons 1 and connected between its ends by straps to iron 6.

The seedbox lla is provided with a metal brace 1lb between its ends, and truss-rods 1lC connect the brace with the ends of the box, so as to make the same absolutely rigid, and as the box is secured to both castings 9 it will serve as a rigid support therefor to prevent sagging.

A collar 13 is secured on each axle-:section beside the casting 9 and is provided with au arm 111, to which a lever 15 is secured by bolts and nuts, as shown. A downwardly springpressed detent 16 is mounted in a housing 16a on one side of the lever 15 and made with a beveled tooth at its end and operated by a hand-lever at the free end of the lever 15, connected with the detent by a rod 18. The detent 16 is adapted to engage a segment 19 on the casting 9,provided throughout the greater portion of its length with inclined ratchetteeth 2O to permit the easy adjustment of the beveled tooth ou the detent and with square teeth 20a at one end of the segment to more securely lock the detent to the segment. The

It will th us IOO be Seer1 that the detent 16 Serves te leek the lever and casting together, and as the latte;` is secured to the frame it will hold the lever in any position to which it may be moved.

Drag-bars 22 are connected to the forward part of the frame by a rod 23, which latter is passed through perforated vlugs 24, depending from iron 3, and through alined holes in the forward bifurcated ends of the drag-bars.

Shoes 25, carrying boots 262M to receive seed from the seedbox, are secured in any approved manner to the drag-bars. Rods 26 are pivotally conneeted at their lower endsy to the shoes 25 and have disposed thereon near their lower ends collars 27, and coiled springs 28 are mounted on the rods 26. springs 28 rest at their lower vends on the collars 27 and bear at their upper ends against collars 29 loose o n the rods.

Short arms 3l, having bearing-sleeves 3,2 thereon for the reception of the axle, are secured to the axle at the angle `desired by setscrevvs 33 yand are bifurcated at their free ends and pivotally connected to collars 29 a pin ,30 passing through the rod 26 above the collar v2 9, so that when the axle-sections lare turned in one direction by levers 15 the arms 3l will force collars. 29 downward .on rods y26, and thus contract springs 28 and force the shoes vinto the grOllnd, and so that when the axle-sections are turned in the reverse direction by the levers l5 the collars 29 will be raised until they strike pins 30 and a continued upward movement of the arms will raise the shoes from the ground.

The seat-support 30L is secured to the arm 6, thus mounting the seat centrally between the levers 15.

The operation of my improvements is as follows: When the machine is to be placed in position for planting, the levers l5 are raised, thus revolving the axle-sections and turning arms 3l to contract springs 28, as above described, and forcing the shoes into the ground. Thedepth of planting can be regulated by the position of the levers, When the levers are lowered, the axle will be turned in the reverse direction and the shoes lifted from the ground. This operation of raising and lowering the shoes does not change the position of the frame in the slightest, and

hence the only work required of the levers is ing any possibility of their sagging under the shoes pivotally connected with the frame, rod

and spring connections between said shoes and crank-arms, a segment securedto the frame and having a bearing for the axle, and a lever secured to the axle and having a latch or detent to engage theseginent.

2. lIn ya grain-drill, the combination .with a frame, wheels and a straight axle mounted in l the hubs ofthe kwheels andextending th rough the traine, of an arm or stub projecting rearwardly from the frame, a .toothed segment secured to the end `ot" said arm or -stnband ha-ving a bearing for the axle, a lever iixed to the axle and adapted to be locked to the toothed segment, hinged shoes, crank-arms on the axle and yielding connections between the crankarms and shoes.
